“Technology News Broadcast: In response to the demand for environmental temperature measurement, the research team has innovatively proposed a dual Fabry Perot fiber optic temperature sensing probe based on end face corrosion. By using special fiber fusion and hydrofluoric acid etching, temperature sensing with small volume, low cost, anti-interference and high sensitivity can be achieved. Tests have shown that the sensor performs well within the temperature range of 28-81 ℃, with a sensitivity of 64.6 pm/℃. This research achievement provides potential application value for small-scale temperature measurement in complex environments.”
